Abstract

(57) [Summary] [Purpose] Efficient mass production is possible, and when spread out, the gap between each elastic block is not conspicuous and the appearance is improved. [Structure] An upper peripheral edge portion 5 which is inclined downward from an upper surface is formed at least at upper end edges of opposite side surfaces, and a side portion of an elastic block 7 adjacent to a side portion where the upper peripheral edge portion 5 is formed is abutted. In this way, the upper peripheral edge portion 5 is also formed on this side portion of the adjacent block 7, and cutting is performed at the inclined surface 9 formed by combining these. This makes it possible to create multiple elastic blocks at the same time with one mold,
Even if these elastic blocks are spread, the gap is difficult to see as viewed from above, and the gap is not conspicuous.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elastic block optimal for a pedestrian passage, an athletics track, and the like, and more particularly, to an elastic block for paving that can be produced in several pieces or continuously and can be easily cut into a predetermined shape.

[0002]

[Prior Art]

 The floors of pedestrian passages, promenades, and athletic courts for athletics, tennis, etc. used to have a soil pavement structure in the old days. It was It has been proposed to eliminate these drawbacks and construct a pavement structure that is easy to maintain by laying multiple blocks made of rubber or elastic synthetic resin to form these passages and coats. Such blocks are mainly made of rubber, urethane or other chip material, or polyethylene, polyvinyl chloride, ethylene vinyl acetate, polypropylene or other synthetic resin granules or foam chips thereof, and the crushing of waste of these synthetic resins. It is made by using elastic particles composed of a single body or a mixture such as a body, and molding and fixing these in a desired shape with, for example, a urethane-based binder. In addition, it has been proposed that an inorganic material such as cement, silica sol, and water glass, various fibers, metals, or the like be mixed as the main body, or that the shape of a slender elbow or a thread is used instead of the granular material.

[0003] Such an elastic paving block can be made into a large amount by forming a strip-shaped continuous body by molding and cutting it into a desired shape. The surface is rough, and there is a gap due to the rough cut surface of the adjacent elastic block when it is spread. Such gaps are not uniform and may differ for each elastic block depending on the degree of roughness, and when the upper end edge has an acute angle, the gap can be clearly seen even when viewed from above and there is roughness. The fluff etc. that are causing the appearance are conspicuous and make the appearance worse.

In order to prevent the occurrence of such roughening, a mold having the shape of a single block is prepared, a mixture of the above-mentioned materials is charged, and the mixture is heated while being pressed by a press to cure the mixture. After that, the product was removed from the mold. Since it is almost in the shape of a product at the time of demolding, the post-treatment is only to trim the burrs generated at the time of mold molding.Since the side surface corresponding to the above cutting surface is smooth, elastic blocks are laid without gaps. can do.

[0005]

[Problems to be solved by the device]

 However, if the molds are made one by one, a large number of molds are required to make a large amount of elastic blocks, which is not economical and the production efficiency is not good.

Therefore, an object of the present invention is to provide an elastic block for paving, which can efficiently mass-produce the elastic block as described above and has a good appearance when paved.

[0007]

[Means for Solving the Problems]

 The elastic block for pavement of the present invention is characterized in that at least the upper edges of the opposite side surfaces are formed with an inclined surface inclined downward from the upper surface.

[0008]

[Action]

 Therefore, the side of the elastic block adjacent to the side on which the inclined surface is formed is brought into contact, and the inclined surface is also formed on this side of the adjacent block so that a cut is made between both inclined surfaces. For example, it is possible to make a plurality of elastic blocks simultaneously with one mold. Since the cutting surface is formed below the inclined surface, even if such an elastic block is laid, the gap is difficult to see as viewed from above, it does not impair aesthetics and it can be mass-produced, so it can be provided at low cost. can do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. The elastic block 1 includes two first and second portions 2 and 3 located substantially in parallel, and these first and second portions. It is formed in a substantially V shape, which is composed of a second portion 3 and a third portion 4 whose end portion is joined to a substantially central portion of the second and third portions. The elastic block 1 is formed such that the upper peripheral edge portion 5 is obliquely cut off. The lower end of the upper peripheral edge portion 5 may be located at a position slightly lower than the surface of the elastic block 1.

As shown in FIG. 2, such an elastic block 1 is made by cutting a strip-shaped continuous body 6 which is molded by a mold (not shown). That is, both ends of the first and second portions 2 and 3 are brought into contact with both ends of the first and second portions 2 and 3 of the elastic block 7 which are adjacent to the substantially central portion of the continuous body 6. Occasionally, a recess 8 corresponding to a gap formed between the both third portions 4 is provided with a gap corresponding to the width of the third portion 4, and the above-mentioned inclined upper peripheral edge portion 5 is It is formed by a mold. As shown in FIG. 3, both ends of the first and second portions 2 and 3 where the upper peripheral edge portion 5 is joined to the adjacent elastic block 7 may form an inclined surface 9 of a substantially inverted triangle. Therefore, the individual elastic blocks can be made by lowering and cutting a punching blade, a wire cutter, a hand saw or the like substantially vertically along the cutting line 10 which is the apex of the inclined surface 9 or by performing water flow cutting. ..

As described above, each elastic block 1 or 7 has a cut surface only on the opposite side surface, but this cut surface is not located up to the upper surface of the elastic block, and the upper peripheral edge portion 5 is formed by the mold. Even if such elastic blocks are spread, the gaps between the elastic blocks 1 and 7 are not conspicuous when viewed from above. In this embodiment, the upper peripheral edge portion 5 is formed over the entire circumference, but it may be formed only at both ends of the first and second portions 2 and 3 which are the cut portions.

In the above-described embodiment, the cutting portion is composed of the inclined surface 9 having a substantially inverted triangle shape. The bottom may be cut so as to be used as a machining allowance. Further, a cutting line portion corresponding to the inclined surface 9 may be formed in the central portion of the bottom portion. Further, although the inclined surface 9 and the upper surfaces of the elastic blocks 1 and 7 intersect each other linearly, the intersection may have a radius.

The upper surface of each of the elastic blocks 1 and 7 is sprayed or coated with resin such as urethane, acrylic and acrylic urethane, synthetic rubber, or synthetic resin such as PE, PVC, EVA and PP, as in the conventional case. Of course, coloring or surface strength may be improved, or water impermeable treatment may be applied, and it is needless to say that unevenness for recognition for persons with disabilities or non-slip processing may be applied.

In the above-described embodiment, the ends of the first and second portions 2 and 3 of the elastic block are formed so as to be connected to the ends of the first and second portions 2 and 3 of the adjacent elastic block. However, the surface of the first portion 2 facing the third portion 4 is formed so as to abut the surface of the adjacent elastic block facing the third portion 4 of the second portion 3 and cut from these portions. You may do it. Also, the shape is taken as an example in a substantially U shape, but it is needless to say that it may be rectangular or polygonal.

[Effect of the device]

 As described above, since the elastic block for paving of the present invention has the inclined surface inclined downward from the upper surface at least at the upper edges of the opposite side surfaces, it is adjacent to the side portion where the inclined surface is formed. By making the side of the elastic block contact, and forming an inclined surface also on this side of the adjacent block and cutting between both inclined surfaces, multiple elastic blocks can be created simultaneously with one mold. can do. Also, since the cut surface is formed below the inclined surface, even if such an elastic block is spread, the gap is difficult to see as viewed from above, it does not spoil the aesthetics, and mass production is possible, so it is cheap. Can be provided.
